Recommended DosageLoading Phase: 20g/day (4x5g) for 5-7 days; Maintenance Phase: 3-5g/day thereafter. Or, 3-5g/day without loading.
Mechanism of ActionIncreases phosphocreatine stores in muscles, improving ATP regeneration for high-intensity exercise, leading to enhanced strength and muscle mass. Increased muscle mass can indirectly boost resting metabolism, potentially aiding long-term weight management, but creatine does not directly burn fat.
Potential Side EffectsInitial weight gain (due to water retention), gastrointestinal discomfort (bloating, diarrhea if large doses consumed without enough water), muscle cramps (anecdotal, not strongly evidenced). Generally safe for healthy individuals.
Verdict (for weight loss)Creatine is not a direct weight loss supplement. Its benefits for body composition are indirect, primarily through enhancing exercise performance and promoting muscle growth, which can secondarily impact metabolism.
Does Creatine Supplements Actually Help You Lose Weight?
Creatine is primarily known for enhancing strength, power, and muscle growth by increasing the body's capacity for high-intensity exercise. While increased muscle mass can lead to a slightly higher resting metabolic rate, indirectly supporting weight management over time, creatine does not directly promote fat loss. Users may even experience an initial weight gain due to intramuscular water retention.

Creatine can support muscle building if you're exercising intensely, but it's not a magic bullet for fat loss.
